What would happen if superman existed? I want to know the specifics, how would I keep my identity safe?
Its about as feasible as 98% of the shit on /x/ anyway, why not?
If Superman existed, you would not have anything to worry about so long as you are not attempting acts seriously harmful to society.
You can't say Superman exists without acknowledging his personality, which in his current interpretation is philanthropic altruist. He would never invade your privacy because "that would be wrong."
